Grails's yesterday in criteria

问题

I'm building a criteria to get all yesterday's created records for a certain domain class. Something like

def c = A.createCriteria().list {
  eq(<some operation on dateCreated>, <some operation on 'now'>)
}

Thanks in advance

How about

Date today = new Date().clearTime()
Date yesterday = today - 1

def c = A.createCriteria().list {
  ge(yesterday)
  lt(today)
}

See example criteria here: http://www.grails.org/doc/1.3.7/ref/Domain%20Classes/withCriteria.html

def now = new Date()
between('dateCreated', now-1, now)

will get you everything created within 24h of now. Just use standard Java date manipulation to set your now to midnight.
